FLOYD DOYLE, or DETROIT, MIcHIeAnl SHIP-RAISING DEVICE.

Application filed September 14, 1923. Serial No. 662,603.

To all whom 'izfimay concern Be it known that I, FLoYo DOYLE, a citizen of the United States, and a resident of Detroit, in the county of \Vayne and State of Michigan, have invented a new and useful Improvement in a Ship-Raising Device, of which the following is a specification.

My invention relates to a new and useful improvement in a ship raising device and has for its object the provision of ship raising device which will be simple in structure, economical of manufacture and highly efflcient in use.

Another object of the invention is the pro vision of a ship raising device having a cable attached to the ship and means for bringing said cable to the surface of the water upon the sinking of the ship, said cable being so arranged as to provide for means for attaching a heavier cable to the ship while in sunken condition.

Other objects will appear hereinafter.

The invention will be best understood from a reference to the accompanying drawings which form a part of this specification and in which- Fig. 1 is a vertical central sectional view of the invention,

Fig. 2 is a vertical central sectional view of the invention, while the ship is in sunken condition, and,

Fig. 3 is an elevational View showing parts in section with the cable wound on the drum.

The invention is designed for providing means for raising a sunken ship by providing means for attaching a cable to the sunken ship and in the preferred form consists of standards 10 and 11 which are securely mounted on the deck 9 of the ship with which used. J ournaled in suitable bearings mounted on these standards is a shaft 12, the size of the shaft and the nature of the standards being determined by the size of the ship to which attached. Mounted on the shaft is a drum having the central portion 16 provided with a bore adapted for mounting on the shaft 12 rotatably. Connected to the portion 16, at opposite sides thereof, are end flanges 17 and 18. The drum is enclosed by a suitable housing 13 having the top thereof tapered as at 14, which terminates in an open neck 15, in which is adapted to engage a buoy 20 which is attached to an endless cable 19 which is wound on the drum. This cable which is of very small diameter is doubled upon the drum portion 16 so as to embrace the portion 16 and the shaft 12. In winding the cable upon the drum the portion 21 is positioned over the portion 22 so as to bind this portion against the portion 16. In winding the cable on the drum the two portions are then wound together. When. the vessel is sunk the buoyancy of the float or buoy 20 serves to unwind the cable thus allowing the buoy to float at the top of the water as shown in Fig. 2.

In using the device for raising the ship the buoy is detached from the cable and a strong cable capable of lifting the ship is then attached to the lighter cable which is passed around the shaft 12. The heavier cable may then be drawn around the shaft 12 by drawing the lighter cable around the shaft. Suitable lifting devices may then be attached to the heavier cable for raising the sunken ship. Any desired number of shafts may be mounted on the ship at proper positions so that when the raising of the ship is being carried out the points of attachment of the shafts will not tear away and will be sufficient to withstand the lifting pressure.

While I have illustrated and described the preferred form of structure I do not wish to limit myself to the precise details of structure shown but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A ship raising device comprising a pair of supporting standards; a housing mounted between said standards; a reel mounted in said housing; and a shaft journalled adjacent its opposite ends on said supporting standards and projected through said housing and said reel for permitting rotation of said reel on said shaft in said housing.

2. A ship raisingdevice comprising a pair of supporting standards in spaced relation; a housing mounted between said standards; a winding reel mounted in said housing; a shaft journalled adjacent its opposite ends in said supporting standards, and projected through said housing and the barrel of said reel for permitting a rotation of said reel thereon.

3. In a ship raising device of the class described, a housing comprising side walls converging toward each other at the upper end and terminating in an outwardly flaring open neck; and a float adapted. normally for resting in said neck, the upper end of said float being withln the terminal limits of said neck.

4. A shlp raising device comprising a pair of standards in spaced relation; a housing mounted between said standards, comprising side walls, said Walls converging sharply adjacent their upper end and terminating in an outwardly flaring open neck, the opposite end of said housing being open; a reel positioned in said housin a shaft journalled adjacent its opposite eiids, in said standards and projected through said housing and said reel, for permitting a rotation of said reel in said housing, said reel being adapted for the Winding and unwinding of a cable thereon; and a float attached to one end of said cable and adapted normally for engaging in said neck, the outwardly flaring walls of said neck permitting easy entry and Withdrawal of said float into and from said neck.

In'testimony whereof I have signed the foregoing specification.

FLOYD DOYLE.
